Hi everyone,
The temperature coefficient(TC) of carbon film resistors are stated as some -200ppm/C and increasing to -800ppm/C for high ohmic resistors.
However, the TC of metal film resistors are often stated as +/- ppm instead of just negative. So,
1. Are there metal film resistors that has positive TC or they all just having negative TC?
2. Does higher ohmic value results in worse TC?
